Abstract

A dental solution dispenser includes a body having a first end, a second end, and including a front housing at the first end, a twist back at the second end, and a grip that interposes the front housing and the twist back. An applicator tip is coupled to the body at the first end, and an ampoule assembly is positioned within the body and includes an ampoule sealed at one end with a frangible seal and defining a fluid chamber for storing a dental solution. A mandrel extends longitudinally within the body and provides a piercing member. The twist back is rotatable relative to the grip to pierce the frangible seal with the piercing member. A trigger is coupled to the body and pivotable between an engaged position, where the trigger engages the ampoule assembly, and a disengaged position, where the trigger disengages the ampoule assembly.
